Peter, Have you tried discharging the built-up charge on the printer between impulses. If the power supply lacks a ground (and therefore the product has no way to bleed off the energy), this could be an issue.
See section 7.1.3 of 61000-4-2 for guidance on how to bleed off the charge between impulses.
